If you want to change it for skill damage, go to battle.c look for:
if( sc->data[SC_EDP] ){ switch(skill_id){ case AS_SPLASHER: // Pre-Renewal only: Soul Breaker and Meteor Assault ignores EDP // Renewal only: Grimtooth and Venom Knife ignore EDP // Both: Venom Splasher ignores EDP [helvetica] #ifndef RENEWAL case ASC_BREAKER: case ASC_METEORASSAULT: #else case AS_GRIMTOOTH: case AS_VENOMKNIFE: #endif break; // skills above have no effect with edp #ifdef RENEWAL // renewal EDP mode requires renewal enabled as well // Renewal EDP: damage gets a half modifier on top of EDP bonus for skills [helvetica] // * Sonic Blow // * Soul Breaker // * Counter Slash // * Cross Impact case AS_SONICBLOW: case ASC_BREAKER: case GC_COUNTERSLASH: case GC_CROSSIMPACT: ATK_RATE(wd.weaponAtk, wd.weaponAtk2, 50); ATK_RATE(wd.equipAtk, wd.equipAtk2, 50); default: // fall through to apply EDP bonuses // Renewal EDP formula [helvetica] // weapon atk * (1 + (edp level * .8)) // equip atk * (1 + (edp level * .6)) ATK_RATE(wd.weaponAtk, wd.weaponAtk2, 100 + (sc->data[SC_EDP]->val1 * 80)); ATK_RATE(wd.equipAtk, wd.equipAtk2, 100 + (sc->data[SC_EDP]->val1 * 60)); break; #else default: ATK_ADDRATE(wd.damage, wd.damage2, sc->data[SC_EDP]->val3); #endif } }   
change to
if( sc->data[SC_EDP] ){ switch(skill_id){ case AS_SPLASHER: // Pre-Renewal only: Soul Breaker and Meteor Assault ignores EDP // Renewal only: Grimtooth and Venom Knife ignore EDP // Both: Venom Splasher ignores EDP [helvetica] #ifndef RENEWAL case ASC_BREAKER: case ASC_METEORASSAULT: #else case AS_GRIMTOOTH: case AS_VENOMKNIFE: #endif break; // skills above have no effect with edp #ifdef RENEWAL // renewal EDP mode requires renewal enabled as well // Renewal EDP: damage gets a half modifier on top of EDP bonus for skills [helvetica] // * Sonic Blow // * Soul Breaker // * Counter Slash // * Cross Impact case AS_SONICBLOW: case ASC_BREAKER: case GC_COUNTERSLASH: case GC_CROSSIMPACT: ATK_RATE(wd.weaponAtk, wd.weaponAtk2, 50/2); ATK_RATE(wd.equipAtk, wd.equipAtk2, 50/2); default: // fall through to apply EDP bonuses // Renewal EDP formula [helvetica] // weapon atk * (1 + (edp level * .8)) // equip atk * (1 + (edp level * .6)) ATK_RATE(wd.weaponAtk, wd.weaponAtk2, (100 + (sc->data[SC_EDP]->val1 * 80))/2); ATK_RATE(wd.equipAtk, wd.equipAtk2, (100 + (sc->data[SC_EDP]->val1 * 60))/2); break; #else default: ATK_ADDRATE(wd.damage, wd.damage2, (sc->data[SC_EDP]->val3)/2); #endif } } Re-compile.

If you want to change EDP status in general go to status.c, look for:
case SC_EDP: val2 = val1 + 2; // Chance to Poison enemies. #ifndef RENEWAL val3 = 50*(val1+1); // Damage increase (+50 +50*lv%) #endif if( sd )// [Ind] - iROwiki says each level increases its duration by 3 seconds tick += pc_checkskill(sd,GC_RESEARCHNEWPOISON)*3000; break;  change to
case SC_EDP: val2 = val1 + 2; // Chance to Poison enemies. #ifndef RENEWAL val3 = (50*(val1+1))/2; // Damage increase (+50 +50*lv%) #endif if( sd )// [Ind] - iROwiki says each level increases its duration by 3 seconds tick += pc_checkskill(sd,GC_RESEARCHNEWPOISON)*3000; break;  Re-compile.
 
Let me know if it works.

I didn't read all of the script but I assume all the members will also be in the same map. So why don't you use a script to give items to everyone in that particular map.
 
Here's a reference that might be useful. http://rathena.org/board/topic/86286-get-map-player-list/
Instead of giving one random person apple, edit that script to make it give apple to everyone in the map by adding a for-loop like so:
prontera,150,150,5 script Give Item 100,{ set(.player,getcharid(3)); deletearray(.players[0],128); addrid(1); set(.players[getarraysize(.players)],getcharid(3)); detachrid; attachrid(.player); for(set @i,0; @i < getarraysize(.players); set @i,@i+1) {     getitem(512,1,set(.@a,.players[@i]));     npctalk rid2name(.@a)+" got a Apple!"; } end; } This code is untested.

SOLVED I've added my own status icon for it and had to make it priority_red in order to overwrite the null_status_icon in order for it to work
